Smartphones can now be used as laboratory-grade medical testing devices thanks to new kit designed by the University of Illinois. The transmission-reflectance-intensity (TRI) analyzer attaches to a smartphone to examine blood, urine or saliva samples as reliably as large, expensive equipment, but costs just $550. The technology uses a high-performance spectrometer. First, a fluid sample is illuminated by the phone’s internal white LED flash, then the light is collected in an optical fiber . The light is then guided through a diffraction grating into the phone’s rear-facing camera, and a reading is provided on-screen. Retrofitting medical technology onto smartphones isn’t anything new. We’ve already seen innovation in HIV testing and fertility tracking , for example. But researchers say the TRI analyzer boasts a wider spectrum of applications, and the relatively cheap, portable nature of the kit means it could have uses in other sectors such as animal health, food safety and environmental monitoring , as well as health diagnostics. “Our TRI Analyzer is like the Swiss Army knife of biosensing, ” said Professor Brian Cunningham. “It’s capable of performing the three most common types of tests in medical diagnostics, so in practice, thousands of already-developed tests could be adapted to it.” Via: NBC Source: University of Illinois

$550 dock turns a smartphone into a medical lab
Mitch Lowe, a founder of Netflix, has a crazy idea. Through his new startup MoviePass, he wants to subsidize our film habit, letting us go to the theater once a day for about the price of a single ticket. From a report: Lowe, an early Netflix executive who now runs a startup called MoviePass, plans to drop the price of the company’s movie ticket subscriptions on Tuesday to $9.95. The fee will let customers get in to one showing every day at any theater in the U.S. that accepts debit cards. MoviePass will pay theaters the full price of each ticket used by subscribers, excluding 3D or Imax screens. MoviePass could lose a lot of money subsidizing people’s movie habits. So the company also raised cash on Tuesday by selling a majority stake to Helios and Matheson Analytics, a small, publicly traded data firm in New York. Theater operators should certainly welcome any effort to increase sales. The top four cinema operators, led by AMC Entertainment, lost $1.3 billion in market value early this month after a disappointing summer. Read more of this story at Slashdot.
